Vanishing bile duct syndrome (VBDS) is a rare but potentially serious cholestatic liver disease caused by various etiologies, including drugs. We herein report a complicated case of VBDS with acute tubular necrosis (ATN) that improved significantly with steroid treatment. An Asian man in his 30s was admitted with the acute onset of severe jaundice and a decline in the renal function. Although initial treatment with ursodeoxycholic acid did not reduce jaundice or renal dysfunction, steroid treatment remarkably improved the VBDS and ATN to within the respective normal ranges. Steroid treatment can be considered in cases of VBDS that appear to have an immune-mediated cause.

Background: Like esophageal varices, cardiac varices are often treated with endoscopic variceal ligation (EVL). However, we previously reported that EVL for cardiac varices may be associated with a high risk of rebleeding from the ulcer if the O-ring spontaneously drops off early. The efficacy and safety of para-variceal endoscopic injection sclerotherapy (EIS) with polidocanol for the treatment of cardiac varices in children and adolescents were evaluated. Methods: Eleven patients under 18 years of age with portal hypertension who underwent para-variceal EIS with polidocanol for cardiac varices with red signs, which were considered to be at high risk of bleeding, were retrospectively reviewed. Results: One session of para-variceal polidocanol-EIS was performed for each of the 11 patients. One patient experienced temporary hypoxia due to aspiration of saliva when the tracheal intubation tube was removed after the procedure but recovered by endotracheal suctioning; there were no other adverse events. In six of the eight cases in which efficacy could be evaluated, eradication of cardiac varices was achieved. Conclusion: Para-variceal polidocanol-EIS may be considered instead of EVL for small cardiac varices with red signs in pediatric patients with cardiac varices.

Objectives: To our knowledge, the relationship between appetite and sarcopenia in patients with cirrhosis is unknown. The aims of this study were to examine the factors associated with decreased appetite and to clarify the relationship between appetite and sarcopenia. Methods: This study included 61 patients with cirrhosis. The patients were asked to describe their appetite using a numerical rating scale (NRS) from 0 (none at all) to 10 (most), with ≤5 defined as decreased appetite. The clinical characteristics, gastrointestinal symptoms as assessed using the Gastrointestinal Symptom Rating Scale, handgrip strength, and skeletal muscle area at the third vertebra were collected retrospectively. Sarcopenia was diagnosed according to the criteria of the Japan Society of Hepatology. The differences in these factors between patients with and without decreased appetite, and the factors associated with the presence of sarcopenia were examined. Results: Alcoholic liver disease was the most common etiology. The median Model for End-Stage Liver Disease score was 8 (interquartile range = 7 - 10) and hepatocellular carcinoma was present in 35 patients. Overall, 36% of the patients with cirrhosis had decreased appetite. Patients with decreased appetite had a higher frequency of abdominal pain and acid reflux–related symptoms and significantly lower handgrip strength than patients without, among both men (P = 0.034) and women (P = 0.017). The multivariate analysis identified a decrease in appetite as a significant factor associated with the presence of sarcopenia (NRS one increase, odds ratio, 0.701; 95% confidence interval, 0.502–0.977; P = 0.036). Conclusion: Decreased appetite was associated with the presence of sarcopenia.

Objectives: The presence of myosteatosis is one factor associated with poor prognosis for patients with cirrhosis; however, the factors contributing to worsening myosteatosis are, to our knowledge, unknown. The aim of this study was to clarify the changes in myosteatosis, and the factors involved in these changes. Methods: The present study enrolled 178 patients with cirrhosis who underwent computed tomography twice to measure changes in skeletal muscle attenuation (SMA) at the L3 level. Factors associated with SMA and those associated with changes in SMA were examined. Results: Using linear multiple regression analysis, age (β = –0.22), skeletal muscle index (SMI; skeletal muscle area divided by height squared; β = 0.25), and visceral and subcutaneous fat indices (VFI and SFI; the visceral and subcutaneous fat areas at the umbilical level divided by height squared; β = –0.08, β = –0.06, respectively) were identified as associated with SMA. The 100-d change in SMA was –0.21 ± 1.29 Hounsfield units (HU). Changes in SMI and SMA were positively associated (R = 0.183, P = 0.014), whereas those in VFI and SMA were negatively associated (R = –0.172, P = 0.022). No association was noted between the 100-d changes in SFI and SMA. In patients whose SMI increased and VFI decreased, the 100-d change in SMA was 0.24 ± 1.82 HU, which was marginally different from that in patients whose SMI decreased and VFI increased (–0.44 ± 1.32 HU, P = 0.077). Conclusions: In patients with cirrhosis, myosteatosis progressed, and decreases in SMI and increases in VFI were correlated with its progression.

Background/Aim: A porous glass membrane-pumping emulsification device (GMD) enables the formation of a high-percentage water-in-oil emulsion with homogeneous and stable droplets. Although GMD is expected to improve the locoregional therapeutic effects of transarterial chemoembolization (TACE) in hepatocellular carcinoma (HCC), its effectiveness in the management of solitary HCC remains unclear. Patients and Methods: Patients treated for solitary HCCs (<5 cm) were retrospectively reviewed. A total of 46 patients who could not undergo liver resection and were unsuitable for radiofrequency ablation were included in this study. Among these, 22 patients underwent TACE using a GMD (GMD-TACE group) and 24 underwent stereotactic body radiotherapy (SBRT) using a robotic radiosurgery system (SBRT group). Local control rates were compared between the two groups. Results: The median HCC tumour size was 24 mm (range=12-50 mm) and 22 mm (range=8-39 mm) in the GMD-TACE and SBRT groups, respectively; however, the difference between the groups was not significant. Age, liver function test results, or Child-Pugh scores were not significantly different between the two groups. The rate of local control at 6 months after treatment was 100% in both groups. Although the 1-year local control rate was higher in the SBRT group (92.3%) than in the GMD-TACE group (81.8%), there was no significant difference in the log-rank test (p=0.654). No major treatment-related complications occurred in either group during the observation period. Conclusion: TACE with GMD could be considered an effective treatment option for the management of solitary HCC.
